Activates police chases in boss races, similar to the game's beta. I thought it'd also make sense "lore"-wise, as it's implied that the police were on the player's toes all the time and that almost all blacklist racers got busted.
Quirk: If your opponent gets busted, you lose the race (rare occurance).
Open vltEd, select Most Wanted and then import the modscript. Enjoy.
